Outsourcing modelling using a novel interval-valued fuzzy quantitative strategic planning matrix (QSPM) and multiple criteria decision-making (MCDMs)

Abstract

Outsourcing drives companies to focus on: their capabilities, advantages of external resources, and decreasing overall operational costs. Selecting appropriate alliances, which are aligned with the company's strategies, establishes a situation through which the firms can enhance their technical capabilities and achieve new technologies. However, two critical issues in outsourcing modeling should be addressed: how to find strategic indicators for building successful alliances, and how to select these partners. Besides, as the imprecise and vague information (due to a lack of data) existing in the outsourcing models cannot be neglected, the application of fuzzy interval sets could efficiently address the complexity of these problems.To deal with these issues, this paper proposes a two-step interval-based framework for the problem. At the beginning, and for the first time, the novel integration of an interval valued fuzzy (IVF) version of strength-weakness-opportunity-threats (SWOT) technique and the quantitative strategic planning matrix (QSPM) with Gap analysis is designed to find the most effective strategies for the alliance evaluation, and to weight them. In the next step, four interval-valued version of multiple criteria decision-making methods (IVF-MCDMs) are implemented to evaluate the strategic partners.Finally, the results are aggregated with the help of the utility interval approach, and a sensitivity analysis is implemented to assess the robustness of the proposed methodology. To illustrate the efficiency of the proposed approach, a real partner selection problem at a holding car manufacturing factory in Iran is presented.

Improved FMEA based on IVF and fuzzy VIKOR method: A case study of workpiece box system of CNC gear milling machine

“…Meanwhile, upper and lower bounds of triangular fuzzy numbers can be defined as interval numbers to ensure that uncertain information can be accurately expressed. [28][29][30][31] Compared with triangular and trapezoid fuzzy numbers, interval-valued triangular fuzzy numbers (IVF) have more advantages in addressing uncertain information. Diversified views of FMEA members can be expressed flexibly and accurately through interval triangular fuzzy numbers.…”

“…The objective weights are calculated using mathematical methods based on the objective information provided by the original information and ignores the expertise and experience of FMEA members. Barak et al 29 proposed an innovative framework that combines SWOT-IVF QSPM with gap analysis. In this method, four different IVF-MCDM algorithms are used to find the best alternative.…”

“…To solve the above problem, instead of defuzzification, we consider using multiple criteria decision making (MCDM) technology to construct an accurate decision information index, and use this index to rank failure modes. Meanwhile, upper and lower bounds of triangular fuzzy numbers can be defined as interval numbers to ensure that uncertain information can be accurately expressed 28–31 . Compared with triangular and trapezoid fuzzy numbers, interval‐valued triangular fuzzy numbers (IVF) have more advantages in addressing uncertain information.…”

Business Development Strategies Using SWOT Analysis in the Cahaya Modern Home Industry

“…The most important variables in the internal environment are the strengths and weaknesses of the organization, while the most important variables in the external environment are opportunities and threats (Indrajit, 2013). After knowing what are the internal and external factors of the Cahaya Modern SMEs the next stage is to do calculations on IFAS and EFAS matrices, Internal-External matrix (IE) to position the company into a matrix consisting of 9 cells (H Setyorini et al, 2016), SWOT matrix, and Quantitative Strategic Planning Matrix (QSPM) which objectively shows which strategy is best (Barak & Javanmard, 2020;Ghorbani et al, 2015;Mallick et al, 2020). The purpose of this study is to determine the internal conditions (Strenghts, Weaknesses) and external (Opportunities, Threats) of Cahaya Modern SMEs by using SWOT analysis so it is known which strategies can be used for business development in Cahaya Modern SMEs.…”

Impact of Supply Chain Management Practices on Supply Chain Performance in Iranian Oil and Gas Companies

“…Along these lines, the partnership helps upgrade an enterprise's performance from different perspectives. Through coordinated effort and division of tasks, they may amplify singular enthusiasm as well as offer the dangers of their tasks Barak & Javanmard (2020). believe that cautious strategic planning and good partnership preparation are fundamental for union achievement in Iran.…”
